1 Claim.

The invention relates to a shade fixture and more especially to a windowshade raising device.

The primary object of the invention is the provision of a device of thischaracter, wherein a 5 window shade hung upon a window can beconveniently raised and held in an adjusted raised position, the devicebeing hung from the head of the window frame and is located above theshade, centered with respect thereto and connected so 10 that the shademay be unwound from its roller and held in an adjusted position.

Another object of the invention is the provision of a fixture of thischaracter, which is simple in its construction, thoroughly reliable andeffective 5 in operation, possessing few parts, being strong, durable,easy of operation and inexpensive to manufacture.

With these and other objects in view, the invention consists in thefeatures of construction,

combination and arrangement of parts as will be hereinafter more fullydescribed, illustrated in the accompanying drawing, which discloses thepreferred embodiment of the invention and pointed out in the claimhereunto appended.

In the accompanying drawing:

Figure 1 is a fragmentary elevation of a window showing a shade hungthereon with the fixture constructed in accordance with the invention inassociation therewith.

' Figure 2 is an enlarged fragmentary sectional view taken on the line2-2 of Figure 1 looking in the direction of the arrows.

Figure 3 is a sectional view taken on the line 3-3 of Figure 1 lookingin the direction of the arrows.

Figure 4 is a sectional view taken on the line 4-4 of. Figure 3 lookingin the direction of the arrows.

Figure 5 is a sectional view taken on the line 5-5 of Figure 4 lookingin the direction of the arrows.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawing.

Referring to the drawing in detail, A designates generally a portion ofa window frame being of conventional make-up, and B, a window shade,which is carried upon a roller l0 and is 50 adapted to be wound on orunwound from such roller in the adjustment thereof, the roller being ofspring winding type and is journaled in shade roller brackets ll, thesebeing fastened to opposite sides of the vertical portions of the window55 frame. It is preferable to have these brackets H support the shaderoller l0 approximately midway of the length or height of the windowframe A for shading the upper half of such window in the use of theshade.

The fixture constituting the present invention 5 for effecting theadjustment of the shade B comprises a relatively narrow housing [2forming spaced perpendicular parallel side cheeks It. This housing I2 ispartially closed at its back l4 and bottom l5, respectively, while thefront and a portion of the top of the housing is opened and formed withthe top area of said housing [2 and projected laterally from the sidecheeks I 3 thereof are attaching flanges It for accommodating fastenersI! so that the housing can be made secure to the head I8 of the windowframe, being preferable to have the housing located at the longitudinalcenter of said window frame.

Formed in the cheeks iii of the housing l2 and opening through the freefront edges thereof are diagonal slots [9, these being inclined inwardlyin the direction of the vertical plane of the window frame A and extendapproximately centrally with respect to said housing l2. Removably ac--commodated within the slots I9 is an axle 20 having a squared terminal2| which fits one of the slots l9 snugly so that the axle, when engagedin the housing, will be held against rotation; This axle 20 rotatablysupports a sprocket pulley 22 over which is trained a link chain 23, itslinks being engageable by the sprocket teeth of said pulley 22 so thatthe latter will be positively driven on pulling upon the chain which atone end has connection with the reinforced end 24 of the shade B throughthe medium of a link 25 loosely engaged in said end and with theendadjacent thereto of the chain. This chain at the other end in thisinstance has connected therewith a pull string 26, although the same maybe dispensed with.

The pulley 22 has formed therewith a disk 21 provided with an annularperipheral flange 28 eifecting a recess 29 in this disk and pivoted at30 to the disk 28 within the recess 29 isa gravity ratchet acting dog 3iadapted to engage in a notch 32 provided in an annular shoulder 33 onthe axle 20 for the latching of the pulley 22 on the said axle 20 atdetermined intervals of rotation of such pulley on making adjustment ofthe shade B so that it will be held in an adjusted postion with relationto the window frame A. The disk 2'! of the frame 28 creating the recess29 effects a boxing for the dog or. pawl 3| and the annular shoulder 33on the axle 2B. The pulley is susceptible of free rotation on the axle20 in one direction and is latched through gravity action of the pawl ordog 3| when rotated in the reverse direction so that the shade can belatched in an adjusted position on unwinding thereof from the roller I0.

The chain 23 has its attachment with the shade at a point verticallyaligned with the mounting of the housing l2 on the window frame.

What is claimed is: v

A shade fixture comprising an upright frame constituting a housinghaving spaced side walls provided with slots inclined inwardly of thehousing and opening upwardly through the said side walls, a center pinpassing through the slots and a a provided with an angular endcontacting with the edges adjacent thereto of one of the slots to holdthe pin against rotation, a sprocket rotatably mounted upon the centerpin, a gravity actuated dog pivoted to the sprocket, a notched discfixed to the pin and having the dog engageable with the notch in saiddisc, and a sprocket chain engaged over the sprocket, said sprockethaving an elongated recessed wall accommodating the notched disc and dogand maintaining the chain against riding on? the sprocket, being guidedbetween said wall and a side wall or the frame which are arranged atopposite sides of the sprocket.
